Earth’s rising seas are some of most visible signs of our warming planet. Over the last 20 years, NASA satellites, airborne missions and field campaigns show a steady rise in global sea levels as the world’s polar ice sheets melt. As the Earth continues to warm, new research suggests sea levels could rise by as much as several feet in the next 100 years. Sea level rise is one of the biggest environmental challenges of the 21st Century, and NASA research is helping us understand how much our oceans will rise, and how fast that will happen. Hear from NASA scientists about the latest research on rising sea levels and melting polar ice.
